I do a search for "hyper-v" in the search box and don't see it. I also searched for it inside the control panel and it's not there. In the turn on windows features in the control panel, I see that everything hyper-v is still checked.
The Hyper-V management tools are now a Microsoft Management Console snap-in. Run
mmc and choose "Add/Remove Snap-in" from the File menu. Select the Hyper-V manager and press the
Add > button in the middle to enable it. (If you get a dialog asking for extra configuration info, fill it out and hit OK.) Click OK to close the Add/Remove Snap-in dialog. The selected tools snap into the MMC instance.
From there, you can expand its "folders" in the left pane and click an entry to modify/configure it in the main window.
